SOLDERING APPARATUS.

SPECIFICATION forming part of L'etters Patent No. 250,598, dated December 6, 1881. Application filed September 7, 1881. (No model.) Patented in France May 23, 1881, and in England June 25, 1881.

To all whom it mag/concern:

Be it known that I, FRIEDRICH S'roLL, Jr., a subject of the Emperor ot' Germany, residing at Stuttgart, Kingdom ot' IViirtemberg, Empire of Germany, have invented new and useful Improvements in Soldering Apparatus, of which the following is a specification,

This invention relates to that class of soldering-irons for the use of tinners, plumbers, and other like workmen, in which vapor generated from liquid hydrocarbon contained in a reservoir forming part of the implement is used as fuel for heating the soldering-head to the required temperature.

This class of soldering-irons possesses many advantages over the old method of heating the irons in portable furnaces which are carried from place to place, according to the requirements of the work to be done, as all liability of accidental fires is obviated, and for the further reason that the soldering-head can be kept constantly heated at a high temperature, thus avoiding the inconvenience and delay occasioned in reheating the same.

The object of my invention is to produce a soldering-tool which shall be of cheap and simple construction and effective in operation, the arrangement of the parts being such that the heat of the burning hydrocarbon is caused to impinge upon or be carried directly to the soldering-head, thus insuring rapid and perfect heating of the same. This object I attain by the construction and arrangement of parts iln lustrated in the accompanying drawings, in

which- Figure 1 represents a side elevation of a soldering-tool constructedaccording to my invention. Fig. 2 is a central vertical section of the same. Fig. 3 is a view of the removable combustion-chamber, showing a modified form of soldering-head 5 and Fig. 4 is a detached view of a cap or cover for closing the oil-reservoir.

In the drawings, A indicates the hydrocarbon-reservoir, preferably made of metal and conical in form, so that the bottom will form a base for the implement, so that when set in an upright position there will be no danger of its tipping or falling over.

B indicates a metal wick-tube, screw-thread ed at one end, which fits into a corresponding thread cut in the top of the reservoir. At the opposite end ofthe wick-tube is a cock, C, hav

ing a lever, D, and passage E, by which the ilow of vapor to the combustion-chamber may be regulated or shut off entirely, as may be desired.

Fis the handle of the implement, secured to the wick-tube which passes through it, and is made of wood or other suitable non-conducting material, so as to preventiujury to the hands by burning.

An ordinary lamp-wick is inserted in the wick-tube, and extends from the cock C down into the reservoir A a suflicient distance to supply the requisite quantity of liquid hydrocarbon to the wick-tube, where it is converted into gas or vapor to be burned in the combustionchamber.

The combustion chamber Gconsists of a metal tube slightly larger in diameter than the wick-tube, so as to lit over the end of the same, as shown, and is provided with air-passages H and igniting-openings I. This tube is open at its outer end, and is formed into or has secured to it two short standards, K K, between which is secured the soldering-head L by means of pivots l, tting into corresponding holes in the standards.

The soldering-heads are preferably made of copper, and may be of the ordinary hammer shape,as shown in Figs. 1 and 2, or pointed, as shown in Fig. 3.

The tube forming the combustion-chamber may be removed when desired, and the implement used as a lamp for heating or lighting purposes, and when the parts are disconnected from the oil-reservoir the mouth of thc latter can be closed by the screw-cap M.

The operation is as follows: The reservoir A being filled with liquid hydrocarbon-such as coal-oil, gasoline, naphtha-and the wicktube containing an ordinaryla-mp-wick inserted in the top of the same, the liquid will, by the capillary action of the wick, be drawn up into the upper portion of said wick-tube. The cock C is then closed and the end of the wick-tube heated by an alcohol-lamp or other suitable means for the purpose of converting the liquid into gas or vapor. When sufficient gas or vapor is thus generated the cock is opened and the vapor escapes through the passage E into the combustion-chamber, Where it may be ignited through the openings I, and the heat passing out through the top of the chamber IOO will impinge directly upon the soldering-head detachable combustion chamber secured ou audkeepit constantly heated atahigh and uuithe end of the wick-tube and provided with form temperature. lateral air-openings and an open end, and the What 1 claim issoldering-tool connected with the open end of 5 The combination of the hydrooztrloou-reserthe combustion-chamber, all substantially as r 5 voir having a. ztt bottom adapt-ed to support shown and described.

itin an upright position, the rigid Wick-tube F. STO'LL, JR. B, attached at one end to the mouth of the res- /Vitnessesz ervoir, and provided at itsother end with a CARL FiSCHER,

Io cock, C, for regulating the flow of vapor, the FRANZ STIEWING.
